UPS systems are frequently "sized" in terms of kW (kilowatts) and/or kVA (kilovolt-amperes). A 1 kVA UPS, for example, signifies that its circuitry can take 1,000 volt-amperes. The fundamental method for calculating alternating current power is "watts = volts x amps." So, a 1,000 VA UPS should be capable of handling 1,000 watts, correct?
